JAMES GARDNER ARCHER, OF BROOKFIELD, MISSOURI.

HAY-SLING.

SPECIFICATION forming part of Letters Patent No. 407,316, dated July 23,1889.

Application filed November 30, 1888- Serial No. 292,177. (No model.) v

To all whom it may concern.-

Be itknown that 1, JAMES GARDNER ARCH- ER, a citizen of the UnitedStates, residing at Brookfield, in the county of Linn and State ofMissouri, haveinvented certain new and useful Improvementsin Slings forHay-Stackers; and I do declare the following; to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to devices used in stacking hay; and it consists ofan improved sling or hammock for holding the hay, and also of certaincombinations and arrangement of elements, as hereinafter set forth, andparticularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the apparatus readyto receive the hay. Fig. 2 is a side elevation of the casing for thespring-bolts, partly broken away. Fig. 3 shows a load of hay readyfol-hoisting,

and Fig. 4 is an end view of the sling withxout the hay.

The center post A is preferably made in two parts 61,66, hingedtogether, so that they can be folded for transportation. The foot of thepost is stepped in a socket in the plate I and its head is provided witha pintle adapted to turn in the plate 0, from which run guy-ropes D,stretched over posts E, set up at suitable distances from the centerpost.

Near the .top of the center post are attached two arms F, which extend,preferably, at right angles with the post and diverging slightly, sothat their outer ends stand considerably apart. The arms are supportedby rods f, running from the top of the center post to the outer end ofthe arms, which are united by a cross-bar F. At the inner and outer endof each ttllll F is a pulley f, and on the socket-plate 1?, or 011 thecenter post near its foot, is a double pulley b. The center post andarms constitute a derrick or crane for hoisting the hay; but this formsno part of the present invention.

The sling or hammock comprises two bars G G, united by cords or wires H.The bar G is provided with two rings or links 9 near its ends. Fastenedto the bar G are two pulleys g. Two ropes I, attached to a bar J runthrough the double pulley b and over the pulleys f down to the pulleysg. Their ends are attached to straps is, fastened to the ends of a barK. On this bar is a casing K, in which are contained two spring-bolts L,normally pressed outward by the springs l. The bolts project through theends of the casing and through holes formed in standards lo adjacent toends of the casing. Hinged to the end of each strap is is a curved hookin the end of which is an eye. The hook is so arranged with reference tothe casing K that it can be turned down in to the space between theeasing and the standard 70, with its eye in line with the bolt L, so asto be engaged thereby, as shown in Figs. 2 and 4c. The inner ends of thebolts L are attached to cords M, which lead out through suitableopenings in the casing. By means of these cords the bolts can beretracted when it is desired to release the hooks W.

The method of using my invention is as follows: The sling or hammock isspread out fiat on the ground, as shown in Fig. 1, with the links gdropped over stakes N, driven in the earth to prevent the sling frombeing displaced. The hay is then raked upon it, and when a suflicientquantity has been gathered the bar G is brought up near the bar K, andthe links 9 are passed over the hooks M, which are then turned down andlocked by the bolts-L. Power is then applied to thebar J either by handor preferably by attaching a horse to it, and a tension is put upon theropes I. This draws the bars G and K toward the bars G and gathers thehay upinto a tight bundle, as shown in Fig. 3. When the bundle has beenhoisted to the arms F, the derrick can be turned by means of the handleA, so as to bring the hay over any desired spot, and then a sharp pullon the cords M will withdraw the bolts G, thereby allowing the hay tofall.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. A sling for a hay-stacker, consisting of the bars G G, united by thecords H, the pulleys g, attached to the bar G, the ropes I, passingthrough the pulleys, and means for and release the bar IOC detachablysecuring the ends of the ropes to attached to the bar K, s the bar G,substantially as set forth. forth.

2. The combination, with the bar G, having' the links g, of the bar G,having the pul- 5 leys g, the cords II, uniting the bars, the bar K,having the hooks 71: and carrying springbolts adapted to engage with Thehooks, and

the ropes I, passing through the pulleys g, and

presence of two witnesses JAMES GARD Witnesses:
